1. Material Preparation

The first step in manufacturing SUS 304 stainless steel is the careful selection of raw materials. The primary components include iron, chromium (18-20%), and nickel (8-10.5%), with minimal amounts of carbon and other alloying elements. The quality and proportions of these materials are critical as they directly influence the final properties of the stainless steel.

Key Techniques:

• Alloying: The precise control of alloying elements ensures the desired mechanical and corrosion-resistant properties are achieved.
• Quality Inspection: Before processing, raw materials undergo inspection for chemical composition and physical properties to confirm they meet required specifications.

2. Melting

Once the raw materials are prepared, they are melted in an electric arc furnace (EAF) at temperatures reaching 1700°C. This high-temperature environment allows for the complete fusion of the metals, creating a homogenous molten alloy.

Key Techniques:

• EAF Melting: Utilizes electrical energy to melt the raw materials, offering better control over the melting process and resulting in fewer impurities.
• Degassing: This process removes dissolved gases from the molten metal, enhancing the quality and preventing defects in the final product.

3. Forming

After melting, the molten SUS 304 stainless steel is cast into slabs or ingots, which are then rolled into sheets or other shapes. This forming process is critical in determining the material’s final dimensions and properties.

Key Techniques:

• Hot Rolling: Involves rolling the material at high temperatures to achieve the desired thickness and surface finish.
• Cold Rolling: May follow hot rolling to enhance the surface finish and achieve tighter tolerances.

4. Assembly and Shaping

Once the sheets are produced, they are cut and shaped into specific components as per the application requirements. This can include various techniques such as stamping, bending, or welding.

Key Techniques:

• CNC Machining: Computer Numerical Control (CNC) machines are utilized for precision cutting and shaping, ensuring high accuracy and repeatability in production.
• Welding: For applications requiring assembly of multiple components, welding techniques such as TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) may be employed.

5. Finishing

The finishing stage involves surface treatments to enhance the appearance and corrosion resistance of the SUS 304 stainless steel. This can include polishing, passivation, and coating processes.

Key Techniques:

• Passivation: A chemical treatment that removes free iron and enhances the formation of a protective oxide layer, improving corrosion resistance.
